Evaluation of open approach and injection laryngoplasty in revision thyroplasty procedures.

INTRODUCTION

Vocal outcomes after medialization laryngoplasty are variable and may change over time. A revision procedure via open approach or an injection laryngoplasty may be necessary to improve vocal outcomes.

METHODS

A retrospective chart review was performed.

RESULTS

Twenty-nine subjects were identified and stratified into group 1A (n = 9) if the allograft was repositioned/replaced, group 1B (n = 4) if the allograft was removed, and group 2 (n = 16) if an injection laryngoplasty was performed. Statistically significant differences were found between all data prerevision to postrevision (P < or = 0.05) for group 1A and group 2 when multiple paired-sample t tests were calculated for patient-reported voice severity ratings and voice impact ratings as well as clinician-reported voice ratings of grade, roughness, and breathiness. Results of group 2 were often temporary, with 10 of 16 (62.5%) subjects receiving multiple injections.

CONCLUSION

Both open revision laryngoplasty and injection laryngoplasty are successful at providing improved vocal outcomes. Results are often temporary after injection laryngoplasty and often require multiple procedures.
